The book of Proverbs has much to say about diligence in work leading to good results (10:4; 12:11; 24, 27; 13:4, 11; 14:23). Skill and knowledge concerning one’s affairs, and orderliness will all be rewarded (22:29; 27:23; 30:25ff.). While diligence will include a good use of time (22:29), a frantic use of time is of no value (21:5). The diligent man plans and does not need to be in haste. Toiling and having in mind riches for one’s own sake is not wise (23:4) says Grant Thorpe. Hence, in our diligence in work, we should be calculative and productive in the use of time so as to yield better, inspiring results.
According to Grant Thorpe, If a man is diligent, he will be able to commit the results of his labours to God, and not eat the bread of anxious toil (Psalm 127:1-2). The implication is that man may finish a day’s work in a day, and rest at night (cf. Eccles 5:9-12). The Decalogue assumes that a week’s work can be done in a week (“Six days you shall labour and do all your work” Exod. 20:9) and that rest follows, as was the case with God’s creation. A man may come to the end of his life knowing he has done what he was given to do (John 17:4; II Tim. 4:6f.). Birds neither sow, reap, or gather into barns, and have no need to be anxious; but man does sow, reap, and gather, and he is not at liberty, having done that, to be anxious (Matt. 6:25-34).
In other words, God feeds the birds without their sowing or reaping, but they do the work for which they were created, and God takes care of them. In the same manner, he will take care of us – not in idleness or improvidence, but if we do the work for which God created us, in diligence, not minding constraints, serving the necessities, and laboring in all thy capacity, we will find favor in love with God.
Therefore, we should work diligently and not merely amuse our self in idleness so that we may find favor in the sight of God and of man through the work of our hands since the harder you work, the luckier you get.
